Determination of dimethyl adipate capillary column

Details of capillary column for determination of dimethyl adipate:



Dimethyl adipate was synthesized with adipic acid and anhydrous methanol as raw materials and sodium bisulfate monohydrate as catalyst. The effects of molar ratio of alcohol to acid, amount of catalyst and reaction time on esterification were investigated. The optimum reaction conditions for the synthesis of dimethyl adipate were determined: n (adipic acid): n (anhydrous methanol): n (sodium bisulfate monohydrate)=1:5:0.29, reflux and water separation for 60 minutes. The yield of dimethyl adipate was 97.48% and the purity was above 98%. The experimental results showed that, Sodium bisulfate monohydrate has good catalytic activity for the synthesis of dimethyl adipate



Haohan Chromatographic (Shandong) Application Technology Development Co., Ltd. has developed a gas chromatographic method for the determination of dimethyl adipate. The area normalization method has been used for quantitative analysis with satisfactory results.
